An Environment Agency-backed code of practice for assessing sustainable drainage systems (SuDS) technologies has been published by British Water, the first such code for the UK.
Water supply chain body British Water is now looking for a partner to install and run testing equipment after publishing the voluntary code, which took two years to create.
It will be used to measure how well devices such as pumps or valves treat runoff water from storms and remove heavy metals and other pollutants from the water cycle.
“Standards are necessary to demonstrate how well proprietary devices used in sustainable drainage systems (SuDS) treat run-off and remove heavy metals from the water cycle. Until now, there was no standard for testing in the UK,” said British Water technical director Marta Perez.
“This code of practice defines the process necessary to measure the pollutant capture and retention capability of any device entering the UK market.”
Professionals delivering SuDS can use the code to minimise environmental pollution. The tested devices are typically used to treat runoff water from urban and residential hard-surfacing such as roads and car parks.
